Understanding life on the molecular level requires knowledge about protein-protein interactions (PPIs), but experimental data is limited and complex, rendering computational methods indispensable. We first analyzed PPI interfaces in all known PPI structures and found surprising differences in binding modes. Then we developed a method based on artificial neural networks that predicts from sequence which amino acids interact in a PPI. Another new state-of-the-art method determines whether two proteins interact. Third, addressing the problem of missing protein annotations in network-based analysis, we developed a function predictor that relies only on sequential similarity to proteins with known annotations.
